Abstract (en)
[origin: EP0827370A2] A resonance type power converter unit has, in an inverter circuit in which voltage driven type semiconductor devices (Q1, Q2) each having the function not to prevent a backward current are connected in series, the respective voltage driven devices (Q1, Q2) are associated with capacitors (C1, C2) which are charged or discharged with currents flowing through the devices and voltage detectors (6, 8) for detecting voltages of the capacitors (C1, C2), and drive circuits (5, 7) for turning on and off the voltage driven devices (Q1, Q2) in accordance with outputs of the voltage detectors (6, 8). With the resonance type power converter unit, stable resonance operation synchronous with a high-frequency load current can be warranted. <IMAGE>
